WATER GAUGE FOR HEATING- BOILERS.

Application filed April 10, 1922. Serial No. 556,967.

T all whom it may concern:

Be it known that I, AN'roNI SWAROCZKY, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful improvements in Water Gauges for Heatin Boilers, of which the following is a specification.

@ne of the objects of this invention is to provide a furnace for heating the water of steam or hot water boilers of conventional type, with means for automatically and positively indicating the level of the water contained in the boiler of steam or hot water heating systems.

Another object is the provision of means for superseding the type of tubular water glasses for an improved mechanically operated indicating gauge of great simplicity and that may be manufactured at low cost.

These and other objects, which will become more apparent as the description progresses, are attained by the novel combination and arrangement of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure and in which Figure '1 is a front elevational view of a water heating furnace.

Figure 2 is a vertical sectional view of the same.

Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 2.

Figure 4 is a vertical sectional view of the indicator. r

Referring to the drawing in detail, the numeral 1O designates, in generalfan oblong rectangular furnace casing, supported by a base 11 and provided at the front with entrances closed by. hinged doors 12. 13, 14 respectively. Secured interiorly of the casing 'are angle irons 1-5, on which is supported a water heating chamber 16, having a central vertical annular opening 17 and a plurality of vertical heat radiating fines 18 disposed parallel to the casing walls, a dome 21 is fitted to the top of the casing in the usual manner.

Extending inwardly thru the side of the casing are a pair of tubular connections 22' and 23 threadably engaged thru the adjacent walls of the water chamber 16, the upper connections 22 being arranged at a point above which water should not be allowed to rise and the lower connection 23 is positioned at the lowest point of the chamber.

A pair of tubes 24- and 25 are threadably engaged at one end in tubular connections 22, 23 respectively and their opposite ends are secured radially thru the side of a vertically disposed tubular float chamber 26, the bottom being closed and the upper end open and communicating with the interior of a hollow semi-circular casing 27.

Another cylindrical tubular chamber 28 is similarly connected to the opposite end of the casing 27 and is also closed at its bottom end and disposed in a vertical parallel position with respect to the chamber 26.

Mounted transversely thru the sides at the center of the casing 27, is a rotatable shaft 29, to which is secured a grooved wheel 30, a flexible element 31 is disposed in the groove of the wheel 30, one end being attached to a float 32 and the'opposite end attached to a weight 33.

The diameter of the wheel being such as to allow the float 32 to move vertically in the dhamber 26 and also to allow the weight 33 to operate in thechamber 28.

Secured to the front side of the casing 27 by abezel 34. is a dial plate/35 pierced at its center, receptive of the extending end of the shaft 29, to which is secured an indicating pointer- 36, adapted to show in connection with graduations onthe dial. the amount or height of water contained in the boiler.

The weight of the float 32., being greater than that of the weight 33, is disposed to find a position of-rest at the lowest part of the chamber 26, -in which position the pointer 36 indicates zero on the dial 35 showing no water in the boiler, but as water is introduced into the boiler, it flows thru the tubular connection 25 and the chamber 26 causes the float 32 to rise and the weight 33 to be lowered into the chamber 28 by gravity.

The flexible element 31, by engagement with the wheel 30. causes the pointer 36 to rotate in clock-Wise direction and indicates the amountof water admitted to the boiler.

From the foregoing description it will be seen that a practical means has been dis closed for mechanically indicating the quantity of water contained in the boiler of a,

heating furnace and superseding the danger- 011s and unsatisfactory tubular water gauge ofcom entional type.

Having thus describet'i my inventiongwhat I claim as neu and desire to secure by Letters Patent, i's:--

A water gauge comprising a hollow substantially semi-circular easing, a horizontally disposed bottom wall at the lower end of the casing, ashatt extending transversely through the casing, a Wheel secured to the shaft Within said casing. the bottom wall of said casing having a pair of spaced open ings therein, tubes secured to the bottom of the casing in alinement with the openings,

assesses a float in one of said tubes, at counterweight in the other of said tubes, a flexible element connecting the float to the weight, said flexible lement extending over the Wheel, a pipe connecting the float containing tube with a boiler in line with the Water level thereof, a pipe connecting the lower end of the float containing tube with the boiler near its lower end. a graduated dial on the casing, and an indicating hand on the shaft movable over the face of the dial to indicate the height of water Within the boiler.

In witness whereof I aflix my signature.
